Abstract: Solid woven conveyor belting is produced by a process which includes the steps of subjecting the fabric carcass to a plurality of alternating changes of direction while immersed in a bath of impregnant material, and then heating the carcass to gel the impregnant. Each of the alternating changes of direction are effected by causing the carcass to follow a generally curved path whose radius of curvature is appreciably less than 75 mm. Prior to immersion, a synthetic polymeric yarn-containing carcass is subjected to a shrinking treatment effective to close the interstices of said carcass to some extent to reduce the impregnant material expelled upon subsequent heating to gel the impregnant.

In a first stage, a coated and heat-set fabric, constituted of longitudinally running warp cords and laterally running picks interlaced with the warp cords, is subdivided into a plurality of elongate tapes, each tape having a lesser number of warp cords than the fabric and picks of reduced linear extent. The tapes are then wound into respective packages. In the second stage, the tapes are unwound and divided each into a plurality of independent warp cords free from the picks. The warp cords are then wound into respective packages.

Abstract: A process for producing fibre-reinforced plastic tubes outfitted with flanges, wherein a tube is continuously knit and coated with a duroplastic material in free-flowing form, and the duroplastic material is subsequently hardened. The application of duroplastic material to the knitted tube is halted at intervals for periods which, allowing for the particular rate of production of the plastic tube, correspond to the period of time in which a piece of knitted fabric sufficient for the production of two flanges is produced. The uncoated piece of knitted fabric is cut in the middle and flanges are formed one at a time in a separate operation in which the knitted fabric is stretched radially outwards and impregnated with duroplastic material which thereafter hardens.
